Initial Evaluation of the Performance of Prototype TV-Band White Space Devices - July 31, 2007
Conclusions: This report determined that the sample prototype White Space Devices (WSD's) submitted to the Commission for initial evaluation do not consistently sense or detect TV broadcast or wireless microphone signals. Our tests also found that the transmitter in the prototype device is capable of causing interference to TV broadcasting and wireless microphones.
However, several features that are contemplated as possible options to minimize the interference potential of WSDs, such as dynamic power control and adjustment of power levels based on signal levels in adjacent bands, are not implemented in the prototype devices that were provided.
Given these results, further testing of these devices was not deemed appropriate at this time.

So....the question to be asked seems to be.... will they try again?
